Jodie bought some shirts for $6 each. marge bought some shirts for $8 each. what was the least amount they could have spent

Least amount they would spend is $40

Step-by-step explanation:

Given:

Jodie bought some shirts for $6 each

Marge Bought some shirts for $8 each

To Find:

Least Money they spent = ?

Solution:

Least money they  would spent would be the LCM of the values which means that the least common multiple of the values

so for finding the LCM we will make prime factors of both values we have

Now

Factors of 6 = 2 * 3

Factors of 8 = 2*2*2

Common Factor = 2

Remaining factors = 3,2,2

Now

LCM = Common factor * remaining factor

So

LCM = 2*3*2*2

        = 40

SO their LCM is 40

Which means that least value they would spend would be $40

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
